A Simple Protocol for Efficient N-Chlorination of Amides and Carbamates
N-Chlorination of various amides, lactams, and carbamates with very cheap trichloroisocyanuric acid proceeds efficiently under very mild conditions. Excellent results were also observed for the N-chlorination of carbamates of free amino acids.

Simple One-Flask Method for the Preparation of Hydroxamic Acids
[reaction: see text] A one-step conversion of carboxylic acids to hydroxamic acids under very mild conditions is described. This simple and efficient method has been applied for the synthesis of enantiopure hydroxamate of alpha-amino acids and peptides.

Microwave‐Assisted Solution‐Phase Synthesis of 1,4,5‐Trisubstituted Pyrazoles
A small parallel library of 1,4,5‐trisubstituted pyrazoles was prepared in solution using a three‐step procedure starting from Meldrum acid. The Meldrum acid was acylated with different acyl chlorides and the products opened with different alcohols and amines to give substituted β‐keto esters and β‐keto amines. Further reaction with N,N‐dimethylformamide dimethylacetal and the final cyclisation were effectively carried out under microwave irradiation. Scavenger resins were employed exclusively in the first step, whereas use of microwaves allowed complete conversion of the starting materials in the other two steps. (© Wiley‐VCH Verlag GmbH & Co.
